No problem. Frustratingly, people rarely seem to talk about how they use RabbitMQ in practice. Also, there are a lot of things that are still a mystery to me (for example, best practices for dealing with things like server shutdowns, or what to do when a NACK "fails", etc).
I need to poke around Hutch and steal some ideas for an RPC implementation. We're just using fire-and-forget type work for now, but I'd love to be able to use RabbitMQ w/anonymous reply queues as a workaround for PHP not being able to do asynchronous RPCs.
